Here's mine solution: (http://pastie.org/226949)

class Parse
  def initialize(rules)
    @rules = create_rules(rules)
  end

  # Read the rules and transform then into regexp
  def create_rules(rules)
    rules.collect do |r|
      vars =[];
r=Regexp.escape(r.chomp).gsub("\\\[","[").gsub("\\\]","]").gsub
/\[([^\]]+)\]/, '(?:\1)?';
      r.gsub!(/<([^>]+)>/) do vars<<$1; '(.*?)' end
      [Regexp.new(r),vars]
    end
  end

  # Parse the given file upon the rules created
  def parse(data)
    @match =[]; @exceptions=[]; data.each do |l|
      mdata=nil; @rules.each_with_index{|(r,d),i| break if !((mdata =
[i,r.match(l)]) == [i,nil]) }
      if !mdata[1].nil?
        @match << ["Rule #{mdata[0]+1}:",*mdata[1].to_a[1..-1]]
      else
        @match << ["# No Match"]; @exceptions << l
      end
    end; self
  end

  #Print results
  def to_s
    "#{@match.collect{|m| m.join(" ")}.join("\n")}" +
    (@exceptions.empty? ?  "" : "\n\nUnmatched
input:\n#{@exceptions.join("")}")
  end
end

# Example of usage
puts "#{Parse.new(File.read("rules.txt")).parse(File.read("guardian.txt"))}"
